[pulseaudio-discuss] Pulse Audio 4.0 gets killed by 300 Hz tone...never recovers

[Robert Krakora]

Hi All,

I have been struggling with Pulse Audio since version 2.1 to play different
wav files that play fine with straight ALSA.  A co-worker found a 300 Hz
tone that is played by our system to warn of an emergency event kills Pulse
Audio 3.0 and 4.0.  The tone sounds like it is motor-boating.  After
playing this tone, wav files that previously sounded fine now also
motor-boat.  Suspending Pulse Audio and playing with straight ALSA is the
only remedy.  ALSA plays all of these wav files just fine.  I really like
Pulse Audio and need it for the WebRTC echo cancellation it provides for
our A/V conferencing application.  However, it struggles with some of the
most basic wav files that our system needs to play on a daily basis.

Best Regards

Rob
